Anymore you guys could add would be a great help to everybody out there trying to find these hard to pinpoint items. Information like map + zone within map and mercs who sell consumable would be a great help thnx everyone for your support

Flamethrower comes from Sparkfly Fen, the north part of the zone, in the old fortress that's filled with ghost pirates.

Deployable Mortar Kit is in Fireheart Rise, up in the northeast part of the zone, there is an event where mortars shell a Flame Legion encampment and you have to kill a veteran on top of a tall tower. After the event the NPC will sell the mortar kit.

I don't remember exact names of locations and I can't log in to find them till Tuesday.
